D. 6Explanation
The given question asks about the number of zeros at the end of the complete result of multiplying 34, 45, and 56. To determine the number of zeros, we need to find the number of factors of 10 in the multiplication. Since 10 is the product of 2 and 5, we need to find the number of pairs of 2 and 5 in the multiplication. In this case, there are three pairs of 2 and 5, resulting in six zeros at the end of the complete result.Rate this question:

Correct Answer
C. 608607Explanation
To find the value of the expression, we multiply each number by its corresponding place value and then add them together. In this case, we have 6 multiplied by 100,000, 8 multiplied by 1,000, 6 multiplied by 100, and 7 multiplied by 1. When we calculate this, we get 600,000 + 8,000 + 600 + 7, which equals 608,607. Therefore, the correct answer is 608607.Rate this question:
